If the package for your install disc looks like the one on uscutter website, http://www.uscutter.com/Flexi-Starter-8-6-Dongle-All-Driver-Edition-SASFLXSTDNGL , then there should be two dics. One is the Flexi Extreme Training disc and the other is your installation disc labeled SAi Production Suite Flexi8.6v2. The second is a dvd. If you look at the bottom of the disc it should read something like DVD 1103 for Windows OS.
Hope this helps to clarify.
